Dfns Wallet for Cardano using cardano-serialization-lib and Mesh

Dfns wallet integration with Cardano wasm and mesh, makes working with Cardano as simple and painless as possible.

The DfnsWallet uses generateSignature to compute signatures using your Dfns managed wallets, for all the transactions created by your program. Then you need to broadcast these transactions yourself to the corresponding node providers that are either self hosted or by a blockchain provider.

A typical setup routine looks like this,

import { DfnsWallet } from '@dfns/lib-cardano-csl'
import { DfnsApiClient } from '@dfns/sdk'
import { AsymmetricKeySigner } from '@dfns/sdk-keysigner'

const signer = new AsymmetricKeySigner({
  privateKey: process.env.DFNS_PRIVATE_KEY!,
  credId: process.env.DFNS_CRED_ID!,
  appOrigin: process.env.DFNS_APP_ORIGIN!,
})

const dfnsClient = new DfnsApiClient({
  appId: process.env.DFNS_APP_ID!,
  authToken: process.env.DFNS_AUTH_TOKEN!,
  baseUrl: process.env.DFNS_API_URL!,
  signer,
})

return DfnsWallet.init({
  walletId,
  dfnsClient,
})
Copy

We made DfnsWallet implement the mesh ISigner interface so the integration with mesh for signatures is easier
